Application filed January 27, 1910. Serial No. 540,402.

To all whom it may concern:

Be it known that I, URBAN Jonnicnn, a citizen of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Dust- Collectors, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention has relation to improvements in dust-collectors for vacuum cleaning systems; and it consists in the novel details of construction more fully set forth in the specification and pointed out in the clalm.

1n the drawings, Figure 1 is a vertical middle section of the invention, with parts in elevation; Fig. 2 is a horizontal plan, and

section on the line 2 2 of Fig. 1; Fig. 3 is a horizontal section on the line 3+3 of Fig. 1;

Fig. 4 is a sectional detail on the line 4 -4 of Fig. 1; and Fig. 5 is an enlarged vertical sectional detail of the fitting carrying the pressure gage, and relief valve.

The present invention is an improvement on the dust-collector forming the subject matter of my U. S. Letters Patent numbered 935,558, dated ()ctober 5, 1909, and has for its object to simplify the patented construction in minor particulars the advantages of which will be clearly apparent from adetailed description of the invention which is as follows Referring to the drawings, C represents an outer casing or vacuum chamber of sheet metal provided with an upper angle-iron ring 1 and a closed bottom 2, the vertical wall of the casing having secured thereto a hollow tee 3, the lower leg of which is provided with a conventional relief or. safetyvalve 4 controlled by a spring 5, the upper leg being provided with a pressure gage 6 of any approved construction. Suspended from the ring 1 is the strainer or filter, which in the present case is composed of an inner fine mesh wire screen a bearing against an enveloping coarse wire grating Z); an outer coarse wire grating b enveloping a fine mesh wire screen a between which and the grating 7) is confined a filter of hair it or similar fibrous material as shown. The filtering or strainer cylinder thus formed is closed at the lower end by a sheet metal bottom 7 or dust pan, provided with a flaring or conical reinforcing flange 7 which snugly embraces the tapering lower end of the outer Wall of the cylinder. lhe upper and lower ends of the innermost layer a are reinforced by sheet-metal bands 8, 9 respectively, a band lOencompassing the upper end 0f the outer wall of the cylinder opposite the band 8. The bands 8, 1O serve as substantial carriers for the bolts 11 by which is secured in position the upper annular filler block 12 which forms thedirect supporting member of the filter cylinder or strainer.

Forming an integral part of the-upper filler block 12 is an outer flange 13 along the bottom of which is disposed an annular rib 14: which fits in a corresponding groove formed alon the upper face of the horizon tal leg of the ring 1, a gasket m in said groove making a tight joint with the rib. 0n the top face of the flange 13 and directly over the rib 1 1- are disposed two concentric ribs 15, 15, forming between them an annular groove d for the reception of a corresponding rib 16 cast on the bottom face of the detachable lid L, a gasket m making a tight joint between the parts. The lid is provided with handles 17, 17 as shown for better manipulation of the same. To clamp the lid down tightly over the strainer and to the filler-block 12 thereof, 1 provide the edge of the lid with a series of pairs of lugs 18-, and at convenient points on the ring 1 are cast pairs of ears 19 between which is pivoted a screw-threaded latch 20 carrying a wing nut w which, when the latch has been swung upward between the lugs 18, may be screwed down against the lugs and thus tightly clamp the lid to the filler block 12.

To loosen the lid, the nuts to are partly un-.

screwed allowing the latches to be swung outwardly against the edge of the vertical leg of the angle-ring 1 (dotted position Fig. 1) thus leaving the lid free to be picked up by the handles 17. Cast with the lid L is a tube 21 to the outer extension of which is secured the hose H leading to the usual suction-head or nozzle (not shown) used in vacuum cleaning systems. The discharge end of the passage or tube 21 turns upwardly thus projecting the dust-laden air against a glass shell or observation dome 22, so that the operator may observe the condition of the air current and when the dust and dirt have ceased to flow into the strainer. 1n thecleaning of rugs and carpets, nap and slmilar particles accumulate on the m- 'ner surface of the filter web a, and it becomes desirable to clean the surface of this web from time to time so as not to interfere with the filtering operation. For this purpose I provide a circular brush 23 provided with radial arms 24 from the inner ends of which leads a stem 25, said stem passing through a stutfing box S in the lid L. By moving the stem up and down the brush or swab is made to rub against the web aand thus remove the nap and similar adhering particles.

The vacuum chamber or casing C is supported on a base composed of legs 26 (three in the present illustration) mounted on casters or rollers 27, the legs being secured at the top by a ring 28 and at the bottom by a ring 29 on which rests a bottom 30. The casing C is supported on the ring 28, the upper legextensions 26 engaging the bottom peripheral surface of the casing and thus preventing lateral displacement thereof. The bottom plate 30 supports the electric (or equivalent) motor M as well as the vacuum pump or similar exhauster P. The intake pipe 31 of the pump taps the bottom of the casing (Fig. 1), the pump exhausting through the perforated nozzle 32 as usual- To protect the motor and pump against dust and dirt and yet permit access thereto at any time for purposes of cleaning, adj ustment and the like, I provide the supporting base with a shield composed of a stationary metal sheet or section 33, having upper and lower inwardly turned edges 6 forming grooves or ways 9 for the reception of a movable or rotatable section 33 preferably provided with a knob or handle 34 for pur poses of manipulation. That the air may freely circulate in the space within the inclosing shield sections, the latter preferably terminate a short distance from the ring 28 or from the bottom of the casing C resting on said ring. To gain access to the pump and motor the section 33 is shoved or rotated in its ways or grooves g, the required degree, thus exposing the parts Within for purposes of cleaning and adjustment.

The operation of the invention is as follows :The vacuum pump belng started draws the dust laden air through the hose H and passage 21 against the dome 22 ber, the latch-bolts 20 are swung out of en gagement with the lugs 18, 18, by loosening the nuts w, whereupon the lid L is taken off, and then the filter chamber is drawn out through the open top of the casing O and the dust accumulated therein is dumped out. The parts are then replaced and the cleaning proceeded with as before. From time to time the operator may reciprocate the swab 23 up and down by seizing hold of the stem 25 as is obvious.

Having described my invention, what I claim is In combination with a cylindrical vacuum chamber or casing, an upper angle-iron ring disposed along the inner wall of the same, a cylindrical filter chamber spaced therefrom and provided with an upper flanged member, an annular rib and groove connection between the ring and flange, the latterhaving an outer amlular groove, a lid provided with an annular rib engaging said groove, and swinging latch-bolts pivoted to the ring and engaging the lid and drawing the latter into positive engagement with the flanged member of the filter chamber, substantially as set forth.

In testimony whereof I aflix my signature, in presence of two witnesses.
